This study has taken care of the details of the breadth and furrows of epidermal ridges and then statistically demonstrating the significant differences in male and female print density.
The present study was conducted with an attempt to describe the densities of epidermal ridges and it has been successful for supporting the hypothesis that women tend to have a statistically significant greater ridge density than men.

It was observed that patients had a greater number of epidermal ridges between triradius B and triradius C of right hand and it was statistically significant difference (p= 0.026, p < 0.05).
[2, 19] But it should be noted that for the Bosnian-Herzegovinian population, it is found a statistically significant difference for BCRCR with a greater number of epidermal ridges between triradius B and triradius C of the right hand and for BCRCL a greater number of epidermal ridges between triradius B and C triradius C of the left hand.
By the 4th month, the epidermal ridges are nicely developed, but the process is probably not complete before the 6th month of gestation (Alter).

Development of epidermal ridges
coincides exactly with the development of cochlea, so dermatoglyphic study in deaf mutes has an important logical bearing.
